ABSTRACT:
The device of the invention has two journaled wheels each having a rubber strip around its periphery and the wheel peripheries are in contact with the specimen traversing control rods of an electron microscope and the like. As the operator moves the control rods to shift the specimen stage along mutually perpendicular directions along X and Y axes, the rotary movements of the rods are transmitted to the wheels which in turn are connected to potentiometers. The potentiometer of each wheel is connected to an electrical source and the output signals correspond to the position of the specimen stage. The output signals are then connected to a X-Y recorder, to digital volt meters or modified video equipment (TV). As the specimen is scanned, points of interest on the specimen will be designated by XY coordinates and the coordinates enable the operator to readily relocate these specimen positions for photographic or other purposes.
